I really like the idea of having more unicode in the language, but I feel  
these should be fairly limited.

There are times I feel that more operators (especially, as has been  
mentioned, opCross and opDotProduct) would be nice to have, but it's just  
sugar, really.

As an example, while I'd enjoy seeing code like this, I'm not sure I'd  
enjoy writing it (Note that I am prone to exaggerations):

int a = ∅; //empty set, same as "= void"
int[] b = [1,2,3,4,5,6];
a = readInt();

if (a ∈ b) // Element of - "in"
{
   float c = 2.00001;
   float d =  readInt();
   writefln(c ≈ ⌈d⌉ ); // Approximately equal, ceil

   myClass c = getInstance();
   if (∃c) // c exists, i.e. "!is null"
   {
     writefln(√(c.foo)); // I thought this should work in D today, using  
"alias sqrt √;", but it seems the compiler chokes on it. :(
   }

   ∀element∈b // New foreach syntax!
   {
     element *= ¼;
   }
}
